A tricky species for beginners, M. atroides most closely resembles Opegrapha atra in the whitish thallus and small slit-like discs. However, the K+ orange thallus and one-septate spores distinguish it. In Ireland, M. atroides is known only from Counties Kerry, Galway and Donegal. Search for it on hazel.
